To all whom itmag concern:

Be it known that I, ISAAC HIRVI, a citizen of Finland, residing atDaisytown, in the county of Washington and State of Pennsylvania, haveinvented certain new and use: ful Improvements in Scrubbing-Machines, ofwhich the following is a specification.

This invention relates to improvements in floor scrubbing machines andits object is to produce a machine of this class comprising a frame inwhich a rotary perforated water tank is journaled that is' provided withplungers that intermittently engage cam plates, also carried by saidframe, whereby a portion of the contents of said tank are released upona rotary brush disposed immediately below said tank to moisten the samein order that it may perform the scrubbing operation as it rotates.

l/Vith the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed in the following specification, pointed out in the claims andillustrated in the accompanying drawings which form a part of saidspecification and in which- Figure 1 is a front elevation of my improvedfloor scrubbing machine. Fig. 2 is a plan of the same. Fig. 3 is an endelevation. Fig. 4 is a vertical section taken on line 1-4 of Fig. 1.Fig. 5 is a detail of the water feed.

Like reference characters indicate corresponding parts throughout theseveral Views.

My machine comprises the U-shaped frame 1 to the inverted base of whicha handle 2 is secured and said frame is provided with supporting legs 3provided with casters 4E. A brush shaft 5 is j ournaled in the frame 1and is provided with a rotary scrubbing brush 6; one end of said brushshaft projecting beyond the frame 1 as at 7 to carry a toothed wheel 8which meshes with a toothed wheel 9 disposed upon a projection 10 of atank shaft 11 which extends through the water tank 12 and is journaledin the frame 1; the projection 10 being provided with a handle 13 bywhich it is rotated as well as the brush shaft through the medium of thetransmission described. The hollow water tank is formed with three ormore rows of perforations 14 which extend longitudinally of the same andover which a rubber band 15 is normally disposed which band is securedto and carried by a metal plate 16 extending from end to end of saidtank. 17 is a spring disposed about a pin 18 and abutting said plate 16at one end and being'formed upon the pin 18 which pin is connected tothe shaft 11 and projected into an aperture in the plate 16 which plateis slidable longitudinally of said pin.

20 is a lug formed integral with or secured a to plate 16 and projectedthrough an aperture in the tank for intermittent engagement with the camplate 21 secured to the frame 1 adjacent said tank. Contact of said luga washer 19 at the opposite end, said washer with said cam plate willraise the rubber g3;

band and plate 16 off the perforations in the tank against the tensionof the spring 17 permitting a portion of the contents of said tank toescape upon the brush 6 and moisten the same.

To one end of the frame 1 an arm 22 is secured which pivotally carries alever 23 which at one end 1s spring-connected as at 24 to said frame andthat at its opposite end carries a pin 25 passing through an aperture inthe frame and into a socket formed in the axle 11 of the water tank andby removing said pin from said socket the tank may be removed from theframe to be cleaned 0r refilled.

What is claimed is 1. In a scrubbing machine, a frame provided with ahandle, a rotary scrubbing brush mounted in said frame, an aperturedrotary water tank mounted in said frame directly above said scrubbingbrush, manually operable means associated with said tank and brush foractuating the same, cam plates carried by said frame adjacent said watertank, a closure within said tank normally disposed over the aperturedportion of the same and means operatively engaging said closure foryieldingly retaining the same in engagement with the apertured portionsof said tank and means carried by said 1 tank and brush for actuatingthe same, cam plates carried by said frame adjacent said Water tank, aclosure normally disposed upon the apertured portion of said Water tank,a pin, provided with a Washer, connecting the shaft of said tank andpassing through a perforation in said closure and means carried by saidclosure projected through said tank for intermittent engagement With thesaid cam plates as the tank is rotated whereby said closure is displacedfrom the apertured portion of said tank to permit the escape of theliquid contents of the same.

In testimony that I claim the foregoing 15 as my own I have heretoaffixed my signature in the presence of tWo subscribing Wit- Copies ofthis patent may be obtained for five cents each, by addressing theCommissioner of Patents, Washington, I). G.
